Fresh from acting as psych-rock survivor Roky Erickson's backing band on last year's True Love Cast Out All Evil, Texans Okkervil River return with their sixth album proper. It's by no means immediate, but its soaring ambition certainly rewards repeat listens, the band's superior Americana complemented by copious strings, horns and even recordings of hurled filing cabinets. "We Need a Myth" and standout "White Shadow Waltz" recall Arcade Fire at their most impassioned, while elsewhere there are nods to the unashamed cleverness of Talking Heads, with frontman Will Sheff's lyrics never less than intriguing.
